Doctor's Notes on Breast Lumps and Pain

Breast lumps are abnormal masses or bumps felt in the breast tissue. Breast lumps may or may not be painful. Common causes of breast lumps include cysts, other non-cancerous growths, injuries, and infections. Breast cancers are a less common cause of breast lumps. Breast pain is usually caused by infection or inflammation die to injury.

Signs and symptoms associated with breast lumps depend on the cause of the lump. Symptoms can include breast pain, tenderness, warmth, redness of the skin, and discharge from the nipple that may contain pus. Other symptoms can include a hard or firm area inside the breast, an enlarging mass that does not cause pain, a lump beneath the nipple, and puckering or dimpling of the overlying skin.
